Product Description
1. Introuduction
Commercial vehicle diesel engines mostly use DOC+SCR post-treatment system to meet the requirements of national ⅳ and ⅴ emission standards, and the catalytic characteristics of different types of SCR have different effects on the final pollutant emission. a copper-based molecular sieve SCR was obtained in the experiment, and based on a 2.8L diesel engine and a vanadium-based SCR, the steady-state cycle (ESC) and transient emission cycle (ETC) of vehicle diesel engines were run. The emission reduction characteristics of diesel engine pollutants are studied and analyzed. The results show that compared with vanadium-based SCR, the emission reduction efficiency of molecular sieve SCR to engine NO and PM emissions increases by 19% and 33% respectively when running ETC cycle. Molecular sieve SCR has higher conversion efficiency of NO at low temperature, and its conversion efficiency is significantly higher than that of vanadium-based SCR at high space velocity because of its insensitivity to exhaust flow; The emission reduction efficiency of molecular sieve SCR on the number of particulate matter is weaker than that of vanadium-based SCR, reaching more than 7%, and it is easy to decompose large mass particulate matter into small mass particulate matter; Both kinds of SCR have certain emission reduction effect on CO and HC, and the emission reduction rate can reach about 20%.

Company Information
Founded in Shanghai in 2019, Shanghai Jisi Environmental Protection Technology Co., Ltd. is a technology, sales and service company focusing on the environmental protection of industrial exhaust gas; In the same period, a brand new catalyst brand "Hive Tech" was created for the industrial exhaust catalyst market, aiming to provide high-quality catalysts for the market.
The establishment of "Haifu" hopes to make domestic brands occupy a place in this market through continuous R&D investment and its advanced production equipment. Our fully automated production line brings fast response and delivery as well as high quality and stability. Localized production brings high cost performance products, thus breaking the monopoly and leading position of imported catalysts.
The company's main products are precious metal/base metal catalysts for VOC emission reduction, SCR catalysts. In addition to general-purpose catalysts, the company also launched efficient alkane catalysts, S-resistant catalysts and halogen resistant catalysts for various market segments.
In addition, the shareholders and relevant beneficiaries of the Company also act as agents for other environmental protection related products, such as pumps/valves/control components, to obtain the best price through long-term cooperation with suppliers of this type for foreign trade business.
